Rising Damp

Rising Dampness occurs when water rises through the pores of masonry due to capillary action. The extent of dampness can vary due to wall thickness, the size of the pores and the local water table. As the wall becomes wet, hygroscopic salts are carried upwards from the ground and evaporate on the wall surface causing damage to the wall finish and any decorations.

If you live in a semi-detached or terrace house you share a wall (or walls) with your neighbour - this is known as the party wall. It separates buildings belonging to different owners. You must get your neighbour's agreement before you can start any work such as a DPC injection or alternatively the membrane system can legally be installed to your side of the party wall with our disturbing the party wall structure without neighbouring consent.
